The turbine flow meter is mainly composed of instrument housing, deflector, impeller, bearing, and signal detection amplifier.
The housing is generally made of non-magnetic stainless steel, which is directly connected to the pipeline and the fluid flows through it. The casing is the casing of the turbine flow meter. To ensure the tightness of the flow meter, the casing must withstand a certain pressure to connect the components of the entire flow meter to form an integrated structure.
The deflector is usually made of non-magnetic stainless steel or hard aluminum material. It is installed at the sensor inlet and outlet and guides and rectifies the fluid to ensure the normal rotation of the impeller. Of traffic.
The impeller is a rotating component with blades mounted on it, and is generally made of magnetically permeable stainless steel. The impeller rotates under the impact of the measured fluid in the pipeline, and has good magnetic permeability. The operating state of the impeller directly affects the measured result.
2.4 Shafts and bearings:
The shaft and bearing play a supporting role in the turbine flowmeter. It can support the rotating parts and is made of high-quality materials to make it have a certain strength, avoid bending and deformation of the shaft, and ensure the lubrication of the bearing. The shaft of the flowmeter is supported on the ground so that the rotating parts can rotate normally to achieve the purpose of measuring the flow. Shafts and bearings have good wear resistance
